Development of a Hybrid Hands-Off Human Computer Interface Based on Electromyogram Signals and Eye-Gaze Tracking.

摘要

A hybrid bands off human computer interface that uses infrared video eye gaze tracking (EGT) and Electromyogram (EMG) signals is introduced. This system combines the advantages of both subsystems, providing quick cursor displacement in long excursions and steady, accurate movement in small position adjustments. The hybrid system also provides a reliable clicking mechanism. The evaluation protocol used to test the system is described and the results for the hybrid, an EMG only interface, and the standard hand-held mouse are described and compared. These results show that the hybrid system is, in an average, faster than the EMG only system by a factor of 2 or more.
